' The "ejinbodif "ent of the invention as shown in the" first four'figures of the dra wing is especially adapted for use in connection withthe @611 lniions' o r. clds'e'd link type of brake hanger; a partivhe'r'eof, is shown at 10. The

truck frame 11 is preferablyprdvidedwith a projection or arm '12; theouter end whereof isienlar edlaterally orderfto permit the" same tebeslotted orlsocketed, therebypizoviding the' upper and lower walls 13andlt -respectively, connectedfat their inner ends by the vertical ebs15, which are preferably.

made arcuate asshown in dotted lines at 16 p in Figure 2 in order toconform with; the arouate surfaces 17, 17, adjacent the ends of thekeeper blocks 18. The slot or socket in the end of the arm 12 ispreferably made at "a slight inclination as moreclea'rly shown in Figure2, so as to induce the keeper means to slide downwardly with the roundedportions 17 17 seatedion the arciiate webs 15. It is apparent from thisconstruction that acoidental vdisplacement of the keeper means, in theevent of loss'of the locking means, is; less likely, while at the sametime the strains placed on the keeper means will all be transmitted tothe truck frame ,The keeper means consists of a pair of blocks identicalto that shown. in Figure 4;

each preferably provided with the projection or shoulder 19,-int'ermediate of the arcuate snrfaces,17,'17 on the inneror .rear'sideof the blocks. These shoill'der's are intended to extendrinto the recess20 in the arin inter-I mediate ofthe webs 15, 15, and thereby preventshifting of the keeper means in a direction lengthwise of the blocks.Each block 18,

on its apposite face is provided with the longij tudinally disposedgroove 21 intended to receive the upper end of thebrake hanger 10;

the grooves 21 ofcthe two-blocks, when arranged in face to facecrelatlonas shownrin Figure 2, being SUfilClIlfi .to receive the-link lO a ndstillzvpermitzfree oscillation of the link -when'the blocks are injiixtapositionf The upper ahd-lovver-I walls 13 and 14 are each providedwith a slotdispo'sed at right i anglest-o the. main portion of the arm12;

that is to say the slots extend, lengthwise of the socket; The slot 22in the Upper wall 13 is somewhat longerthanthe slot 23 in the lower walll lyand the inner 'en'd'sto f both slots are made sloping outwardl orforward 1y toward the bottom at: an angle substan tially similar to theangle ofinelination of thekeeperblocks.

These slo'tsl22 211 16123are'soparrangedthat' the inner ends thereofwill be; disposed in a vertical planerearward of the forwardedges" ofthe keeper elements when 'the" latter" are completely seated in thesocket formed in the arm 12, see Figure 2. The forward longitudinalsides of the keeper members 18 (which are arranged in superposedrelation) are each provided with a vertically disposed groove or slotasshown at 24, see Figure 4, for'the purpose of receiving the rear edge ofthe wedge member or key 25 when the latter has been driven through slots22 and 23 in the arm portions or walls 13 and 14. The forwardlongitudinal edge of the wedge member or key 25 is intended to bedisposed perpendicular to the ends of the wedge member while the rearlongitudinal edge is made sloping so as to provide a key member taperingtoward the lower end thereof. 1

In practice, the brake hanger 10 has its upper end inserted into thegroove 21 of the lower kee er member or block 18; the upper block 18 isthen put into position with its grooved face downwardly so that thegrooves 21 of the two blocks constitute a suitable channelfor the upperend of the hanger 10. The assembled elements are then inserted into thesocket formed between the upper walls 13 and 14, with the shoulders 19disposed into the rear end of the socket intermediate of the verticalwebs between walls 13 and 14. 1 These shoulders not only center theblocks in proper position, but also prevent lateral or sidewise movementthereof. The key membar or Wedge is then driven into place with itstapered'end disposed downwardly thus causing the forward perpendicularedge to be in'bearing relation with the forward ends of the slots 22 and23 while the sloping rear edge of the key member, which is disposed inthe grooves 24 of both blocks, will be in hearing relation with theforward surfaces of the blocks, without contact at the rear ends of theslots 22 and 23. This causes the blocks to be firmly wedged in place. Itis understood. that the hanger '10 straddles the lower wall portion 14.After the key has been firmlyadriveninto place, the lower end thereofpreferably flexed orbent laterally as shown at 26 in Figure 1 so thataccidental removal of the key is prevented.

. In Figures 5 and 6, I show a modification especially intended for usein connection with the U-shape hanger indicated at 27 having uppereyeletted ends 28 to receive a supportingpin 29. The keeper means, inthis instance, consists of a pair of corresponding blocks 30, 30 ofsomewhat greater length than the blocks or keeper members 18. The endsof blocks 30, 30 are preferably slightly enlarged as shown at 31 andslotted transversely from the rear sides to receive the eyeletted ends28 of the hanger 27 and still permit oscillatory movement of the hanger.These slotted ends are disposed beyond the vertical webs 15, 15 of thearm 12 whereby the upper and lower walls 13 and 14 are connected to---gether. .The appositefaces of each member or block 30 is provided witha longitudinal groove disposed throughout the intermediate or main bodyportion as well as partially into the ends to receive the supporting pin29. The pin receiving grooves terminate a short distance from theimmediate ends of the blocks so as to provide the abutting walls 32,, 32at the ends of the pin 29 and thus prevent longitudinal movement of thelatter. V

. It will be'understood that the keeper mem bers or blocks 30 areidentical in construction and like blocks 18 are interchangeable. Thatis to say, either block may constitute the upper or lower block. Theforward longitudinal sides of the blocks 30 are each provided at aregistering point with a vertically disposed groove 33 adapted toreceive the wedge member or key 25 when the latter is disposed throughslots 22 and 23 formed in the upper and lower wall portions 13 and 1 1like in the previously described construction. The wedge member 25, forthe construction shown in'Figures 5 and 6, as well as the function ofthe slots 22 and 23 are identical with that previously described.

In practice, the supporting pin 29 is inserted through the eyelets 28 ofhanger 27, the pin 29 then placed in the longitudinal'groove of thelower block 30 after-which the upper block 30' is placed thereon withits longitudinal groove encircling the upper side of the supporting pin;the end walls 32 of both blocks completely closing the ends of thegroove and preventing movement of the pin. The assembled elements arethen put into the socket in the arm intermediate of the walls 13 and 14with the hanger 27 straddling the lower wall portion l tlike in thepreviously described construction. The wedge member or key 25 is thendriven downwardly through the slots 22 and 23 with its rear sloping edgein the grooves 330i the keeper members or blocks. The slots 22 and 23,as previously described, are of such length that their rear ends aredisposed in avertical plane rearward of the vertical forwardlongitudinal edges of the keeper elements or blocks so that the wedgemember or key will-not contact with the rear ends of the slots 22 and23. This permits a firm wedging of the keeper blocks in place. The lowerend of the wedge member or key is then preferably flexed or bentlaterally as shown vin Figure 5 at 26 to hold the wedge member firmly inplace.

It is apparent that other means may be used for locking the wedge'memberin place, but the method shown is believed to be the simplestand mostacceptable, because the necessity for employing additional parts orelements is eliminated. v p

With my constructions it is apparent that if any wearshould resultbetween the keeper members or blocks and the cast'metal portions of thetruck frame, .this can :be readily.

taken up by adjustment or further driving of the wedge member intoplace. Furthermore, the wedge member or key when properly driven homewill prevent all chatter or vibration between the keeper member and thetruck frame and thus materially reduce possibility of wear. Furthermore,with'my improved construction, a considerable saving in material andexpense is possible because the method of securing the keeper means inplace enables narrower keeper blocks to be employed than hasheretofore'been'the case.

In order to permit the temporary use of an ordinary brake pin or bolt,in the event of loss of thewedge key while the train is at a distancefrom the shops, I show the intermediate portions of slots 22' and 23 inthe upper and lower walls 13 andM, bowed outwardly or made arcuateasshown at 34 to provide an opening sufficiently large to receive theordinary round pin which is generally accesible along the ri ht-of-way.The slots 2% in keeper blocks or plates 18,'and the slots 33 1 in thekeeper plates 30, at the outer ends, are

therefore flared outwardly in an arcuate' manner as shown at 35 and 36,respectively, see Figures l and 6, to permit the temporary use of anordinary bolt or pin having a round shank. It is apparent that the roundpin will hold the keeper elements with the brake hangers in properposition, permitting proper brake application during the remainder ofthe run, until a replacement of the Wedge-'- key can be made.

The constructions shown are thought to be the simplest and bestembodiments of the invention, but certain modifications may be madewithout, however, departing from the I combination wlth a truck framehavlng a spirit of my invention;
